Aminopurvalanol A (NG 97) is primarily used in biochemical research as a potent and selective inhibitor of cyclin-dependent kinases (CDKs). It is particularly valuable in studying the regulation of cell cycle progression and apoptosis. Researchers utilize this compound to investigate the role of CDKs in cancer development, as it helps in understanding how inhibition of these kinases can potentially halt tumor growth. Additionally, it is employed in pharmacological studies to explore therapeutic strategies targeting CDK activity in various diseases. Its high specificity makes it a useful tool in elucidating the complex mechanisms of cellular signaling pathways.
